OpenGL Error Codes

Error Codes returned by glGetError():

• GL_INVALID_ENUM: given when an enumeration parameter contains an enum that is not allowed for that function.
• GL_INVALID_VALUE: given when a numerical parameter does not conform to the range requirements that the function places upon it.
• GL_INVALID_OPERATION: given when the function in question cannot be executed because of state that has been set in the context.
• GL_STACK_OVERFLOW: given when a stack pushing operation causes a stack to overflow the limit of that stack's size.
• GL_STACK_UNDERFLOW: given when a stack popping operation is given when the stack is already at its lowest point.
• GL_OUT_OF_MEMORY: given when performing an operation that can allocate memory, when the memory in question cannot be allocated.
• GL_TABLE_TOO_LARGE (if the optional imaging subset (GL_ARB_imaging) is supported)
• GL_INVALID_FRAMEBUFFER_OPERATION

Framebuffer Objects have their own error codes for codes for testing framebuffer completeness. The meaning of these codes is defined in the section on framebuffer completeness.
